FOLDING-MACHINE.

Application filed August 16, 1913.

To all whom it may concern:

Be it known that I, GARRY J. DORMANDY, a citizen of the United States, residing at Troy, ltensselaer county, New York, have invented certain new and useful Improvemens in Folding-Machines, of which the following is a specification.

My invention relates to machines for folding and pressing blanks for collars, cuffs and like articles. Its object is to fold the blanks smoothly and correctly and to press the infolded edges after this folding operation.

Particularly, the object of my invention is to provide novel and advantageous means for expanding and contracting the die or templet over which the edges of the blanks are folded.

In the drawings, Figure 1 is a side elevation of a folding machine showing a preferred form of my invention; Fig. 2 is a partial top plan view of the same; F ig. 3 is a front elevation of the part shown in Fig. 2; Figs. 4 and 5 are vertical transverse sections 011 planes l l and 55, Figs. 3 and 2 respectively; Fig. 6 is a partial side elevation of the machine showing a modification.

Referring to the first five figures, 11 designates the frame or standard of the machine, provided at its right end with bearings 12 for shaft 13, Fig. 1, on which is keyed coupling member 1 1, adapted to clutch engagement with loose pulley 15, which may be continuously driven by suitable means, as a belt, not shown. A pedal 16 is pivoted at 17 to floor brackets 18 and carries a rigid arm 19 pivotally connected by bar 20 to arm 21, the upper end of which is fast to rockshaft 22, to which is secured a forked arm 23 connected by pins 24- to the collar portion of clutch member lat. A spring 25 acts through parts 19 to 2d to normally hold clutch members 14, 15 in operative relation. A worm 26 on shaft 13 acts through suitable gears, cams, levers, etc., including links 27, 28, bolts 29, presser block 30, and vertically movable rod 31, to raise and lower the templet support 32, to move inward and outward the folder bars, as 33, to force said bars down toward the bed and raise them therefrom. As all these parts or their equivalents, as well as the operations performed thereby, are well known in the art and form no part of the present invention, I will omit Specification of Letters Patent.

any further description of them, except as may hereafter become necessary to explain the novel features of the machine.

Templet support 32 is shown as integral with rock-shaft 34, which is supported in end bearings 35 at the rear of frame 11. On support 32 is bolted arm 36, at the front, free, end of which is an integral plate 37, to which is bolted head 38, comprising plate portion 39, and two longitudinal bar portions d0 connected thereto by legs d1. At one side of arm 36 is an arm 42 formed with a lateral flange 43. On arm 42 is bolted a part it having flange a5, which coacts with flange to form cam-groove 46 shown as having an upper portion substantially tangential to the arc of the swinging arm 36 and a lower portion at a low angle extending rearwardly therefrom. At its forward end arm 42 is secured by bolts 47 to a plate 48 adapted to move freely between plate 39 and bars 40. Secured to but spaced away from plate 48 is a bar 49, guided for fore and aft movement only by a transverse slot 50 in the lower faces of bars 4L0, in which it has a sliding fit, screws 51, which hold parts 4-8 l-9 together, moving in slots 52 in transverse projections 53 5a in bars 40. Two other slots 55 cut in the lower faces of bars 40 serve to hold plates 56, secured to bars 40 by screws 57, and also hold guide bars 58, to which and to bar 49 is secured by screws 59 a longitudinal bar 60, in which is cut a face groove 61 and which has at its ends top flanges 62. At the middle of bar is secured by screw 63 a block 6 1, to which is in turn secured a short die-bar 65 carrying middle die-blade 66. In bar 60 at each side of block 64 are out two slots 67, through which pass screws 68, which hold in place, but permit longitudinal movement of, right and left sliding bars 69, each formed with a rear flange 7 0 riding in groove 61. To these bars 69 are adjustably secured by means of screws 71 riding in slots 72, L-shaped die-bars 73 carrying dieblades 74%, the ends of bars 73 having, in the present instance, forwardly turned portions 7 5 to support the ends of blades 7 4c. Rising vertically from each bar 69 is a roller pin 77, which moves in a diagonal slot 78 in plate 56. Bolted to the bed 11 which forms the top of frame 11, is a lug 79 carrying a lateral roller pin 80, which engages in cam groove 45.

Premising that the machine as illustrated is set up for infolding blanks for the tops of collars, which require to be folded on one long side and two ends only, and that the particular templet shown and the means for expanding and contracting it are adapted to this operation, the operation is as follows: The machine standing in its stopped position, as shown in Fig. 1, the operator places a blank, ordinarily consisting of two superposed plies of fabric, on bed 11 in proper relation to templet blades 6674E. He then starts the machine by tilting pedal 16, which acts through parts 19 to 24: to engage clutch members 1 1-15. At this time the templet is in its non-operative, contracted position, shown in dotted lines, Fig. 2, that is, the outer blades 7 1 are drawn forwardly and inwardly from their normal position. lhe machine is timed so that the templet support 32 and all the parts connected therewith are first drawn clownward by rod 31 toward bed 11. During the first part of this movement the inclined lower portion of cam groove 16 rides on pin 80 whereby arm 42 and its connected parts are moved rearwardly on arm 36, thereby causing pins 77 to move toward the outer ends of inclined slots 78 and expanding the templet to the position shown in full lines Fig. 2 and in Fig. 3 before the templet reaches its operative position on the blank resting on bed 11*. A further rotation of shaft 18 causes the movement of the infolder blades inward over the templet blades in the usual manner, whereby the edges of the blank are folded, after which presser blocks 30 are forced downward upon the folder blades while these are in their inward position to press and dry the folder edges of the blank on the heated bed. Next, the presser blocks are raised, the folder blades are drawn outward and finally, the templet is raised from the bed, carrying the folded blank. During the latter part of this upward movement of the templet the pin 80 passes through the lower inclined portion of groove 46, forcing arm 12 forward and thus contracting the templet. The machine is then stopped, preferably automatically, when a second similar cycle of operations is begun.

In the obvious modification of the machine shown in Fig. 6, arm 82 is the analogue of arm 12 of the first construction, carries at its forward end the same or equivalent die expanding and contracting means, and differs therefrom only in the means at its rear end by which its longitudinal movement is effected. At its downwardly curved rear end 83 is a laterally projecting roller pin 84 moving in a cam groove 85 in a lug 86 secured as before to the bed 11 of the machine. Groove 85 has its upper portion at an angle with the tangent to the arc in which arms 36 swings, and its lower portion curved to a segment of that arc. Obviously, the operation of the device will be unchanged, in that the initial downward movement of the arm will act to expand the templet, so that it will come down on the blank in expanded position, and that the later portion of its upward movement will contract the die or templet as before, whereby any tendency to either stretch or crumple the blank is avoided.

The present invention is an improvement over that of my pending application filed January 24, 1913, which has received Serial Number 743,982, in that it provides the simple and effective means shown for automatically expanding and contracting the templet during the time of its movement toward and from the bed. This automatic movement of the die blades during their bodily movement shortens the time required for a cycle of the machine, or allows a greater time for the pressing operation in a cycle of given lengt The means shown are simple, strong and, being above the bed of the machine and in plain sight of the operator, cannot work loose or get out of order without immediate detection.

It will be understood that the number or position of the die blades, either stationary or movable, or the particular connecting parts between the moving arm and these blades, is immaterial to my invention.
